Sorry: I was mostly replying to the other commenters who were sahing the science behind stem cell treatments for blindness (embryonic or not) was impossible.
No need to be sorry. You brought some interesting posts to the party! I have a couple of relatives who have been stricken with blindness and my wife worries about her own possible predisposition for macular degeneration.
However, it would have been clearer if you had replied directly to those “commenter” who dissed stem cell cures for blindness.
